Disassembly steps are as follows:
1. Close the two valves of the heating, one is the inlet valve and the other is the outlet valve.
2. At the front of the radiator, it is about 10 cm, and you will see an inclined downward plug with a heating filter installed inside.
3. Unscrew the plug with a wrench of appropriate size, and then take out the filter by hand.
The filter screen in the heating system should be cleaned almost once a year. If it is not cleaned for a long time, the house may not be hot, and cleaning the heating filter is not complicated.
We can try to do it ourselves; The specific steps of cleaning the heating filter screen: first, close the valves on the upper and lower water pipes, and then prepare a spray for receiving water and put it under the filter screen. When it is ready, we can remove the plug of the filter with a wrench; Remove the plug of the filter and take out the filter screen. Rinse the filter with clean water.
Finally, install the filter screen, screw on the plug and open the valve according to the reverse steps mentioned above, thus completing the cleaning of the filter.
